What's going on under the ground? Hydrogeology of Asylum Lake Preserve

Hydrogeology. That's the scientific word for it. Back in the mid-'90s the Department of Geosciences at WMU developed a test site and buried metal drums and pipes in a distant corner of the prairie at the Preserve. Now, every summer, hydrologists from places such as Virginia, Minnesota, Peru, Japan, Denmark, and Norway, come to Kalamazoo for a seminar course that teaches them to monitor the level and quality of the groundwater, and how to detect oil drums, pipes and other items that have been buried underground which threaten the quality of the groundwater in places where the barrels or pipes are rusting or leaking.

Using electric, magnetic, and ground-penetrating radar tools they practice on a far corner of the prairie, learning how to detect the barrels and pipes. They take these skills back home to help clear the environment of buried trash that can cause pollution.

The barrels and pipes buried in the Preserve do not pose a threat to the Preserve. They are clean and nondegradable. You could think of them as "seeds" planted there to help train the growing number of professionals now being employed in the field of environmental studies and ecology.

A second project of the hydrogeology program in Asylum Lake Preserve studies its groundwater. Each summer a special seminar spends a week drawing samples from wells located in the preserve.

Wells? You may be wondering, will someone fall down one of these wells while innocently taking a walk or a run? The simple answer is "never."

These are not the kinds of open wells that people fall into. In fact, it would be a challenge to even find one of them, since the tops are covered with metal plates that are locked and bolted down flat to the surface.

When the water samples are taken to test the flow and quality of the groundwater, seminar students (people from all over the U.S. and the world) camp out in the field next to the wells. They take samples on regular intervals over a 40-hour period and work to protect the site.

Poetry Inspired by Asylum Lake Preserve

Some people come to Asylum Lake Preserve for exercise. Some to walk the dog. Some to simply soak in the ever-changing sights of nature. Others come for inspiration. Whether it be artists, writers, or poets the lakes, trees and grasses encourage the muse.

The poems Green by Conrad Hilberry, and At Last Lynn Pattison, are examples of the inspiration nature provides.

Green

No one else can claim it.
Steep slope west of the path,
oaks, maples, dead grape vines

hanging on, and below, in a slant
of sun, my pond scum lake.
A hundred yards of tight valley,

bushes in the water, nothing
flowing in or out. Stalks bend
east, bowing to the wind

in their reedy way. A click
of cricket, or time
passing through. I frighten

a frog. He jumps and swims
slicing the green silence.
On the way back, a haunt

of notes from Jeff's melodion—
no keyboard, just air pressed out,
pulled in, and buttoned down,

music for an August afternoon.

— Conrad Hilbery

At Last



A woodchuck waddles from the thicket
to lunch on young shoots. The marsh rings
with cries of peepers---Easter creatures, a cross
on each tiny back. I want to wind the trunks

of saplings in blue ribbon, hang flags over
the gate. Soon we’ll clean feeders and brew thick syrup
for the hummingbirds eager for bee balm and bleeding
heart. A clutch of turkeys cuts

across the path, males fanning full displays
Under a mat of leaves daffodils nudge up, appraise
the light. I tie prayer scrolls in the sweet gum,
cut woody vines from trees. Soon,

a haze of green in the treetops and soil
softening. Time for wind chimes of hollow bones,
bottles that whistle in the wind. Mayapples
unfurling, Lilies of the Valley rising. Oven birds.
